Problems solved by technology

[0003] At present, two-component water-based paint can meet the paint requirements for metal parts such as leaf springs and chassis in terms of technical indicators, but when using two-component water-based paint, the two components must be mixed and used within a short time, which is prone to The situation of curing before all of them have been used will lead to waste of materials and even blockage of equipment pipelines. The cost of use is far higher than the cost of solvent-based paints currently used, and beyond the range that manufacturers can afford

Abstract

The invention relates to a water-based industrial paint, particularly a quick-drying single-component water-based anticorrosive finish paint for coating vehicle plate springs and chassis and other metal components. The preparation method comprises the following steps: (1) preparing a mixed paste; (2) grinding the mixed paste to a certain fineness to prepare a graining paste; and (3) adding the rest of materials into the graining paste, and stirring uniformly to obtain the finished product. The finish paint is a water-based product, has very low VOC (volatile organic compound) content, greatly reduces the consumption and discharge of organic solvents, is beneficial to occupational health of production personnel, and is green, environment-friendly and healthy. The product has excellent salt-fog resistance, adhesive force, hardness, drying rate and the like, achieves the product standard requirements, especially has outstanding blocking resistance, and shortens the piling and transportation time after coating the vehicle plate springs and chassis and other metal components. The product has favorable compatibility with the solvent-type anticorrosive primer and water-based anticorrosive primer. The use cost of the product is equivalent to that of the solvent-type product, and thus, the product can be used instead of the solvent-type product, is convenient to use, and has excellent blocking resistance and obvious economic benefit and social benefit.

Description

technical field [0001] The invention relates to a water-based industrial paint, in particular to a fast-drying one-component water-based anti-corrosion finish paint used for coating metal parts such as vehicle leaf springs and chassis. Background technique [0002] At present, solvent-based paints are mainly used for anti-corrosion paints for metal parts such as vehicle leaf springs and chassis. Solvent-based paints themselves contain 30-50% organic solvents, and 10%-30% solvents need to be added for dilution when used. Therefore, When the paint is dry, more than 50% of the solvent by mass volatilizes into the air, causing a large amount of VOC emissions, which not only pollutes the environment, but also wastes petroleum resources. It also poses a hazard to the occupational health of production personnel and is also a source of fire hazard. Therefore, the development and use of environmentally friendly water-based paints is the need to solve environmental pollution, save res...
